Sansürlü ve Budanmış Veriler için Değişim Noktası Problemleri

Yıl 2013, Cilt: 10 Sayı: 1, 85 - 94, 15.07.2013

Öz

Bu makale, Gürler ve Yenigün’ün (2011) merhum Profesör Yalçın TUNCER’in anısına düzenlenmiş olan konferans için hazırlanmış çalışmanın bir özetidir. Gözlemler rastgele sansür ve budanmaya tabi olduğunda tehlike değişim noktasının tahmini dikkate alınmıştır. Tehlike fonksiyonunun tek bir sıçrama yaptığı ve bunun dışında parçalı sabit olduğu varsayılmıştır. Tam ve koşullu olabilirlik yaklaşımları düşünülmüş ve daha iyi performans gösterdikleri koşullar tartışılmıştır.

Hazard Change Point Problem for Censored and Truncated Data

This paper is a summary of the work by Gürler and Yenigün (2011) prepared for the conference in memory of the late Professor Yalçın Tuncer. We consider the estimation of the hazard change point when the observations are subject to random censoring and truncation. The hazard function is assumed to have single jump and otherwise piecewise constant. Full and conditional likelihood approaches are considered and the conditions under which they perform better are discussed.
